“…Nevertheless, G levels at the end of this study increased in the two groups fed the finisher diets containing~488 and 501 g lactose or total sugar/kg, resp., compared with the two other groups fed~385 and 416 g lactose or total sugar/kg, resp. In accordance, high postprandial G levels were measured in veal calves fed high amounts of lactose or glucose (GUILHERMET and TOULLEC, 1983;WIJAYASHINGHE et al, 1984;HOSTETTLER-ALLEN et al, 1994;HUGI et al, 1997).…”

Summary Veal calves often develop insulin resistance, hyperglycaemia and glucosuria. We have studied effects of age and nutrition on blood metabolites and hormones, with major emphasis on glucose and insulin, in four groups of veal calves from 66–69 kg until slaughter at 175–196 kg. Calves were fed milk replacers which differed with respect to lactose, total sugar, protein and fat content. Mean intakes in groups 1, 2, 3 and 4 of lactose (1.24, 1.08, 0.95 and 0.66 kg/d), total sugar (1.27, 1.10, 1.01 and 96 kg/d), crude protein (0.40, 0.48, 0.65 and 0.49 kg/d) and crude fat (0.32, 0.31, 0.37 and 0.46 kg/d) were different. Average daily gains were 1.46–1.49 kg and feed/gain ratios were 1.49–1.61 kg/kg. Glucose and insulin concentrations were not associated with protein and fat intakes, but followed lactose and total sugar intakes, albeit differently at the start and end of the growth trial. Thus, insulin concentrations were higher (P < 0.05) at the end than at start of the growth trial in all 4 groups, whereas glucose concentrations increased (P < 0.05) with increasing age in only group 2. In conclusion, lactose and total sugar intakes affected the degree of hyperglycaemia and modified hyperinsulinemia at a given age, but the age‐dependent rise of insulin concentrations could not be explained by hyperglycaemia alone.

“…Excessive intake of lactose, which is converted during digestion into G and galactose, could have caused hyperglycemia and hyperinsulinemia. Guilhermet and Toullec (1983) reported exaggerated G and I concentrations when large amounts of lactose were fed. When lactose intake was halved, the G and I concentrations increased less and lasted a shorter time.…”

In intensively milk-fed calves post-prandial glucose (G) and insulin (I) concentrations, but not preprandial G concentrations, increased or failed to decrease during the growth period, compared with data from calves that were progressively weaned. This study was, therefore, designed to investigate G and I metabolism in veal calves. Euglycemic-hyperinsulinemic and hyperglycemic clamps in the unfed state demonstrated mutual responsiveness of I and G, but revealed a relative I resistance. After feed consumption, I resistance was exaggerated, as seen by decreased G clearance rates after i.v. G and I administration in fed compared with unfed calves. Milk replacer is a source of readily available lactose, fat, and protein, the intake of which, on a kilogram.75 basis, gradually increased with age. Increased substrate availability and effects of nutrients themselves were probably responsible for elevated plasma concentrations of G and I and led to I resistance. Additionally, hyperglycemia > 1.5 g/L was followed by urinary excretion of G.
